Yes. Nebula projectors with Android TV system support Auto (Vertical ±40°) and Manual (Horizontal ±40°) keystone correction. When you set auto keystone correction to "on", it could only do vertical keystone correction. For horizontal correction, you will need to turn off auto keystone correction and then manually adjust vertical, horizontal, and quadrilateral keystone correction. 

How to turn on/off the keystone correction?

1. Click "Settings".

2. Select the "Projector Settings" option.

3. Turn Auto Keystone correction on, or turn it off to manually adjust vertical, horizontal, and quadrilateral keystone correction.
